Qhov saum npoo ntawm cemented carbide conical kawg mills yog qhov nquag kub hnyiab thiab tawg tom qab ntse, uas cuam tshuam loj heev rau kev ua haujlwm ntawm lub cuab yeej thiab nws lub neej ua haujlwm. Vim li no, peb pom los ntawm kev ua ntau lawm tias kev xaiv ntawm kev sib tsoo lub log nrog qhov loj thiab cov kab nrawm muaj peev xwm tiag tiag zam cov kab nrib pleb thiab hlawv ntawm saum npoo ntawm cemented carbide cov cuab yeej thiab xyuas kom muaj kev txhim kho kom zoo dua qub.
(1) Kev faib tawm, muaj pes tsawg leeg thiab kev siv ntawm cov feem ntau siv cemented carbide
Kev faib hom, tshuaj lom neeg, kev ua tau zoo thiab kev siv ntawm cov feem ntau siv roj av hauv kuv lub teb chaws tau qhia nyob rau hauv Table 1. Cov cemented carbide tsim nyob hauv kuv lub teb chaws tau muab faib ua ob pawg: YT thiab YG. YT hom yog muaj li ntawm titanium carbide, tungsten carbide thiab cobalt. Lub ntsiab cov khoom yog WC, TiC thiab Co. Lawv feem ntau yog siv los ua cov cuab yeej rau kev txiav cov hlau. YG yog lub zog sib xyaw ntawm cov tungsten carbide thiab cobalt. Cov khoom tseem ceeb yog WC thiab Co. Lawv feem ntau yog siv los ua cov cuab yeej txiav rau cov hlau cam, cov tawv tawv hlau, steel hlau, thiab lwm yam, thiab ua rau ntau cov cemented carbide ntsuas cov cuab yeej, pwm, geological mining thiab roj drilling. Siv cov cuab yeej tsuas, thiab lwm yam Ntxiv rau, muaj YW-hom titanium-tungsten-cobalt carbides nrog tus nqi me me ntawm cov hlau carbides xws li tantalum carbide lossis niobium carbide, uas yog siv los ua cov cuab yeej rau kev txiav tshwj xeeb kub-resistant alloy cov ntaub ntawv.
(2) Cemented carbide rau ntau yam cuab yeej
Lwm txoj kev faib tawm yog faib cov ntau hom cemented carbide siv rau kev txiav, tsuas thiab lwm lub hom phiaj rau hauv ob hom: cermet cemented carbide thiab steel bonded cemented carbide.
Erm Cermet cemented carbide yog cov hmoov hlau ua cov khoom siv los ntawm kev sib xyaw ua kom zoo nkauj hlau carbide hmoov (xws li WC, TiC, thiab lwm yam) thiab cov hlua khi (xws li Co, Ni, thiab lwm yam), ua rau nws nyob rau hauv kev nyuaj siab, thiab sintering. Piv txwv li, tungsten-cobalt cemented carbide (YG3, YG6, YG8, thiab lwm yam) thiab tungsten-cobalt-titanium cemented carbide (YT5, YT15, YT30, thiab lwm yam) yog qhov feem ntau siv ntau lawm. Qhov no zoo ntawm cov khoom siv cemented carbide tiv taus qhov kub thiab hnav hnyav, thiab dav siv hauv kev tsim cov cuab yeej ntsuas thiab pwm, nrog rau cov khoom siv tho thiab cov khoom siv tho.
② Cov hlau-sib raug zoo cemented carbide siv ib lossis ob peb carbides (xws li TiC, WC, thiab lwm yam) raws li cov theem tawv, thiab cov hlau alloy (xws li kev kub ceev steel, chromium-molybdenum steel, thiab lwm yam) hmoov ua cov ntawv sau, tom qab sib xyaws, sib xyaw, thiab nias Thiab sintered hmoov metallurgy cov ntaub ntawv. Nov yog hom tshiab ntawm cov khoom siv dag zog, tuaj yeem faib ua ob hom hauv qab no.
a. Qhov feem ntawm kev kub ceev steel sib raug zoo cemented carbide uas muaj TiC yog 35%, thiab qhov sib npaug ntawm cov huab hwm coj uas muaj cov hlau siab yog 65%. Lub hardness tom qab quenching thiab tempering yog HRC69-73.
b. Qhov feem ntawm WC nyob rau hauv chromium-molybdenum steel-sib raug zoo cemented carbide yog 50%, thiab qhov kev faib ua feem ntawm huab hwm coj ntawm chromium-molybdenum steel yog 50%.
Qhov saum toj no yog kev qhia txog kev qhia txog kev txo qis saum npoo ntawm cemented carbide milling cutters, thiab kuv vam tias yuav pab tau txhua tus neeg.
